Deep in the forests or out in the sandy desterts or in the muddy swamps or even in the snowy moutains lies Skeleton villages. With the new Minecraft update, this made Skeletons a neutral mob and don't burn in the daylight anymore, in the day players are fine unless they hit the Skeletons, but at night, they're back to being player hunters. Skeletons now lived in villages, if there are no players around, they live peacefully with each other, but if there is a player nearby, they will have Skeleton (the elite guards) patrol around to keep an eye out for the player. In the different biomes, there are more Skeleton villages, (ex: Parched Skeleton desert villages, Stray Skeleton villages, Bogged Skeleton villages. And even Wither Skeleton villages in the Nether).
